TAKE-UP MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 312,128, dated February 10, 1885.

Application filed August 3, 1%.83.

I0 raZZ whom it may concern.-

Be it known that I, Fnrnnnrcrr Knssnn RING, a citizen of Switzerland, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Take-Up Mechanisms for Looms, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a front View of a loom embodying my invention. Fig. 2 isaside View of the loom,with certain parts broken away and certain parts represented in section. Figs. 3 and 4 are detail views. Figs. Band 6 are sectional views of details.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of novel take-up mechanism.

Referring to the drawings, A represents the frame of the loom, the upper part being supported by columns B, which rest upon the lower part of the frame.

M represents a drum or cylinder, on which the cloth or fabric is wound. To this shaft or cylinder is secured a worm-wheel, M, with which engages a worm, M, on an upright shaft, l\' A collar, N, is fitted loosely to the lower part of the shaft l\ and carries a pawl, I, which engages with a ratchet-wheel, Q, the latter being firmly locked on the shaft M at its lower end. Said shaft is firmly mounted in the frame A at its lower and up per ends. The upper end of this shaft l\' is represented as broken away in Fig. 1. It is surmounted by a handle, M", as shown in Fig. 2. The pawl P is shown in detail in Fig. 5. It has three teeth having play up and down independently of each other through the collar N. These teeth are one behind the other, and are arranged, as shown in Fig. 5, at a little greater distance apart than are the teeth of the ratchet-wheel Q. Any one of them taking against a tooth of the ratchet-wheel will turn it when motion is givenin the proper direction to the collar. Thus the effect of a much finer ratchet is attained,while the teeth are still large enough to be firmly taken against by the pawl and so to transmit the power required without danger of the pawl slipping off.

(No model.)

To the collar N is connected a hooked arm, R, the hook of which is adapted to be taken against by an arm or part-,R,ofthe lay on the backward stroke of the latter, if the hook lies in its path, whereby rotary motion is imparted to said collar N in one direction. The motion in the opposite direction is occasioned by an arm, S, which is connected with one of the supporting-arms S of the reed-frame S, the latter being supported by means of the said arms S, secured on the supporting-shaft S and held in position by a torsional spring, S. Equivalent means may be used in lieu of the spring S for holding the reed-frame in posi tion. The torsional spring which holds the reed-frame in its normal position I prefer to use, and to provide it with aratchet and pawl, the object whereof is to adjust the tension of said spring. This is shown in Figs. 3 and 4, which are detail views of the torsional spring S and connected parts. S is the square torsional spring. One end is seated in a square recess in the plug S, which plug is mounted in the frame of the lay S and held fast by the pawl S, taking into the teeth of a ratchet, S

mounted and keyed fast on the plug and held I fast by the pawl in any position to which it may be initially turned, this giving the initial tension to the spring. the spring S is seated in a square recess in the body of the partly-tubular shaft S, (which is partly solid for that purpose,) which shaft S is mounted as a sleeve on the plug S at one end, and has a reduced portion fitting in the frame of the lay at the other end, and which shaft carries securely locked on it the arms S, which carry the reed-frame S. To one of the arms S is securely'fiistened the arm S. The lay, pivoted at the base of the loom, is driven in the well-known way from the shaft E by means of the cranks E the links E and the rigid arms E of the lay. As the lay moves forward and beats up, the reedframe is caused to yield to the resistance offered by the fabric, owing to its pivotal connection with the lay, and motion is imparted to the arm S. This engages with a stud or projection, It, on the arm It, (shown in section The other end of into position to engage with and turn the latter on the return motion of the arm R, occasioned by the arm or part Rof the lay engaging with the hook of the arm R. The rotation of the ratchet Q is imparted to the shaft M and worm M, whereby the cylinder or cloth-beam M is rotated, and the cloth or fabric consequently wound thereon. The rate of this rotation will manifestly depend entirely upon the distance which the arm R is thrown forward by the engagement of the arm S with the stud or projection R at each beat of the lay, (the said stud being first properly adjusted as to its distance from the hook ot' the arm R and this will depend upon the resistance offered by the fabric to the forward motion of the reed-frame, increasing as that increases and diminishing as that diminishes. The rate of the take-up motion is thus automatically determined by the ability or inability of the reedframe to make its full stroke in beating up. By my arrangement the reedframe is controlled by one single spring, not by two separate springs, as heretofore. and the tension of that single spring is adjustable, whereby the fabric is evenly battened up across the entire width of the goods, and with a compactness that can be regulated at will.

My improved take-up motion also possesses the advantage that there-can be no backward motion of the cloth-beam, and that withouta special locking device, the worm M readily operating the worm-wheel M, but the wormwheel being unable to operate the Worm. Thus the strain of the fabric is held by the frame of the machine.

I do not here claim the shuttledriving mechanism shown in the drawings, since the same' is claimed in a pending application (Serial No. 132,422, tiled by me May 22, 1884) for an improvement in shuttle-driving mechanism for looms; nor do I make any claim to the Jacquard mechanism shown in the drawings.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the cloth-beam M, worm-wheel M, worm 1V shaft 1\ ratchetwheel Q, pawl P, collar N, and hooked arm R, having stud It, with the lay and reedframe of a loom, the reed-frame being pivoted on the lay. and havinga device to hold it in position, and an arm, S, adapted to take against the stud R, and the lay being adapted to take against the book of the arm R, substantially as and for the purposes set forth.

2. The combination of the cloth-beam M, wornrwheel M, worin M", shal't M, ratchetwheel 0, pawl P, collar N, and hooked arm R, having stud R, with the lay and reedframe ofa loom. the arms S. shalt S torsional spring S, plug S", and the arm S, substantially as and for the purposes set forth.

3. The combination of the cloth-beam M, worm-wheel M. worm M, collar N shat't M, ratchet-wheel Q, pawl P, and hooked arm R. having stud R, with the lay and reed-frame of a loom, the arms S, shaft S. torsional spring S, plug S", ratchet S pawl S, and the arm S, substantially as and for the purposes set forth.
